i'm afraid that i can't help on this one, but i have an additional
question: are levels of various neurotransmitters hereditary? in other
words, have there been any studies suggesting that normal/abnormal
levels of chemicals like dopamine and serotonin have a genetic basis?
i'm doing a paper on the hereditary nature of bipolar disorder and
schizophrenia, and i'm intrigued by this part.
thanks!
